3. simplify on both sides

A. Using subtraction, the distance between the two birds = |-2.5 - 2.5| = |-5| = 5 meters.

B. Using additive inverses, the distance = 2.5 + 2.5 = 5 meters

The distance between any two points on a number line is the absolute difference of the coordinates of the two points.

The additive inverse of a number is the number that is added to the number to make it zero. For example, the additive inverse of a is -a.

Part A:

Using subtraction, the distance between the two birds = |-2.5 - 2.5| = |-5| = 5 meters.

Part B:

The additive inverse of -2.5 is 2.5.

Using additive inverses, the distance = 2.5 + 2.5

Using additive inverses, the distance = 5 meters

Step-by-step explanation:

The volume of Ruth's new lunch box is 1,540 cm³.

The volume is a measure of an object occupied in a three-dimensional space.

Volume is a three-dimensional quantity that measures the capacity of a shape or the amount of three-dimensional space a closed figure can occupy.

The formula for computing a volume is height x length x width.

Height = 5 cm

Length = 22 cm

Width = 14 cm

Volume = 1,540 cm³ (5 x 22 x 14)

Thus, the volume of Ruth's new lunch box, showing the three-dimensional space within, is 1,540 cm³.

After solving the equation In (2m + 3) = 8, the value of m is equal to 5/2.

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

We have been asked to find m in (2 m+3) = 8

⇒ (2 m+3) = 8

⇒ 2m + 3 = 8

⇒ 2m = 8 - 3

⇒ 2m = 5

⇒ m = 5/2

So, m is equal to 5/2 in (2 m+3) = 8

The measure of each angle of the triangle is 40°, 40° and 100°.

What is the triangle?

Given:

In an isosceles triangle two of the three angles measure the same.

Let the two angles be equal to x.

The third angle is 20 more than twice the measure of either angle, which means 2x+20.

The angles of a triangle add up to 180 degrees.

(x)+(x)+(2x+20)=180

4x+20=180

4x=160

x=40 degrees

So, the two angles measure 40° each and the third angle would be,

2x+20

=2*40+20

=100°

Therefore, the measure of each angle of the triangle is 40°, 40° and 100°.

The solution of the radical equation of x is 1.

A linear equation in one variable is an equation which can be represented in the form of ax+b where x is the variable and 'a' is the coefficient and 'b' is  the two constants.

A radical equation is defined as an equation where the variable is under a radical or root.

We know that n-th root of a variable x can be written as x to the power of (1/n). Mathematically : [tex]\sqrt[n]{x} =x^{\frac{1}{n} }[/tex]

In the given equation:

∛x-1=√x-1

adding 1 to both sides we get:

or, ∛x=√x

Cross multiplying we get:

or, ∛x/√x =1

We know that (aˣ/aⁿ)=a⁽ˣ⁻ⁿ⁾

therefore :

or, [tex]x^{\frac{1}{3}-\frac{1}{2} }=1[/tex]

or, [tex]x^{-\frac{1}{6} }=1[/tex]

or, x=1

Hence the value of x in the radical equation is 1

The coordinates of the midpoint M are (-1/2, 1), and the length of YZ is approximately 14.32 units.

We have,

To find the coordinates of the midpoint M of the line segment YZ, we can use the midpoint formula:

Midpoint M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the endpoints Y and Z, respectively.

Given:

Y(1, -6) and Z(-2, 8)

Now, apply the midpoint formula:

Midpoint M = ((1 + (-2)) / 2, (-6 + 8) / 2)

Midpoint M = (-1 / 2, 2 / 2)

Simplify:

Midpoint M = (-1/2, 1)

To find the length of YZ, we can use the distance formula:

Length of YZ = √[(x₂ - x₁)² + (y₂ - y₁)²]

Given:

Y(1, -6) and Z(-2, 8)

Now, apply the distance formula:

Length of YZ = √[(-2 - 1)² + (8 - (-6))²]

Length of YZ = √[(-3)² + (8 + 6)²]

Length of YZ = √[9 + 196]

Length of YZ = √205

Length of YZ ≈ 14.32 (rounded to the nearest tenth)

Thus,

The coordinates of the midpoint M are (-1/2, 1), and the length of YZ is approximately 14.32 units.

The correct option is D). The element is sodium, and it is highly reactive.

The atomic number of the element sodium (Na) is 11. It means that the sodium has 11 protons in total and because it is neutral it has 11 number of electrons.

Valence electrons (VE) refers to the electrons that usually presents in the outer shell of an atom. Thus, the sodium has only 1 valence electron.

Answer:

x + y = 29   equation 1 

Five more than means add 5+5 three times the smaller number:

 3x equals the larger number:  = y 3x + 5 = y    equation 2

 From equation 1x + y = 29subtract x from both sidesy = 29 - x 

We now have two things that are both equal tothe larger number y.

  They must be equal to each other. 
3x + 5 = 29 - x

 Add x to both sides 3x + x + 5 = 29 - x + x4x + 5 = 29

subtract 5 from both sides 4x + 5 - 5 = 29 - 54x = 24

divide both sides by 44x/4 = 24/4x = 6 

We now know x = 6

We also know y=29-x y = 29 - 6y = 23

The step 2 is incorrect angle o and angle p form supplementary angles not alternate interior angle that is :

∠o +  ∠p = 180°

What are alternate interior angle ?

An alternate interior angle is one formed on the inside side of two parallel lines and opposite on the outer side of the transversal when those two parallel lines are intersected by a transversal and they are equal.

Alternate angles between a transverse and parallel lines are equal .

Here, the step 1 is correct :

as the sum of angles of a triangle is 180 degree therefore,

∠m +∠n + ∠o = 180°.............(1)

the step 2 is incorrect :

as angle o and angle p form supplementary angles not alternate interior angle therefore it will be :

∠o +  ∠p = 180°........(2)

after that step 3 and 4 is correct to get the final result as :

step 3 : ∠m +∠n + ∠o = ∠o +  ∠p

step 4 : ∠m +∠n = ∠p
